چکیده

Compared to serial robots, parallel kinematic machines (PKM) offer superior properties. However, modelling and analysis of PKMs are challenging tasks due to their complicated kinematic structure. In this paper we present methods to analyze the workspace of a class of 6 degree-of-freedom (dof) PKMs with constant leg length. These methods apply interval analysis in order to calculate the orientation workspace and to verify if a certain machine covers a desired workspace. The machines are assembled from a construction kit that defines components like legs, frames, and platforms.

Optimization of the Kinematic Sensitivity and the Greatest Continuous Circle in the Constant-orientation Workspace of Planar Parallel Mechanisms

This paper presents the results of a comprehensive study on the efficiency of planar parallel mechanisms, considering their kinetostatic performance and also, their workspace. This aim is approached upon proceeding single- and multi-objective optimization procedures. Kinetostatic performances of ten different planar parallel mechanisms are analyzed by resorting to a recent index, kinematic sens...

Dexterous Workspace Shape and Size Optimization of Tricept Parallel Manipulator

This work intends to deal with the optimal kinematic synthesis problem of Tricept parallel manipulator. Observing that cuboid workspaces are desirable for most machines, we use the concept of effective inscribed cuboid workspace, which reflects requirements on the workspace shape, volume and quality, simultaneously. The effectiveness of a workspace is characterized by the dexterity of the manip...

A Comparative Study of Parallel Kinematic Architectures for Machining Applications

Parallel kinematic mechanisms are interesting alternative designs for machining applications. Three 2-DOF parallel mechanism architectures dedicated to machining applications are studied in this paper. The three mechanisms have two constant length struts gliding along fixed linear actuated joints with different relative orientation. The comparative study is conducted on the basis of a same pres...

Kinematic Mapping and Forward Kinematic Problem of a 5-DOF (3T2R) Parallel Mechanism with Identical Limb Structures

The main objective of this paper is to study the Euclidean displacement of a 5-DOF parallel mechanism performing three translation and two independent rotations with identical limb structures-recently revealed by performing the type synthesis-in a higher dimensional projective space, rather than relying on classical recipes, such as Cartesian coordinates and Euler angles. In this paper, Study's...

Orientation Workspace Analysis of a 3-DoF Planar Parallel Kinematic Machine

In this paper, kinematic and workspace analysis of 3-DoF planar Parallel Kinematic Machine (PKM) is carried out. The mechanism consists of three legs in which two legs have Prismatic-RevolutePrismatic joints and other leg has Prismatic-Prismatic-Revolute joints, it termed as 2-PRP and 1-PPR planar parallel kinematic machine. By these joints, the mechanism can achieve two translational motions a...
